The actuator, designed for the DUO system,
allows to activate auxiliary services, such as addi-
tional door locks, staircase-lights, and rings without
adding wires on the riser line. It is provided with one
relay and one IN/OUT configurable port; the port
configured as output (OUT) activates a relay to
manage a second auxiliary service; when config-
ured as input (IN) it acquires information about the
status of the device connected to it, typically a
contact (switch, automatic stop device, etc.) that
sends open/close information.
By programming the device, the acquired information
can be sent on line and made available for other
devices in the system.
Multiple actuators can be connected in the same
installation by suitably programming the addresses
of the relay and the IN/OUT port of each actuator;
moreover, the activation time and operating modes
can be set for the relay and the port that was
configured previously as output.
The operating modes are:
- monostable (upon reception of the command, the
relay and/or port is activated for the programmed
time and then is deactivated)
- bistable (upon reception of the command the relay
and/or port changes its status from activated to
deactivated or vice versa until the next command,
which changes the status of the relay and/or port
again).

c) Connecting the actuator to an additional distributor DV2420
To connect the actuator in the proximity of the external door station or along the line of an
external door station, a DV2420 must be added as shown in the following examples.
- Connection in installation WITHOUT exchanger
(actuator power supply directly from line)
line to external door stations or exchangers
line to video distributors
line to riser
line to external door
stations
